,mvEN-ror? ATTORNEY WITNESSES While the other end 9 of thecoil leaves the j unlon 12, or in any other suitable manner, the end o' the pipe 11 connectedlto the pipe 9 hein the end of the coil oi' pipe 11 near tile en aust manifold, while the other end of the pipe coil 11 has a continuation 13 t leerling to a carhureter 14C, and from the can otlie casing 15 from i `inffludi'ng a pressure gage 26. i The pipe25 bureter another pipe 15 leads to ,and opens into the intake manifold 2.

At the end 8 of they pipe 7 there is agevernor 16 comprising a suitable casing with a float 17 therein carrying a valve 18 eX- teudi 'g through `and seating Vin a diaphragm 19 dividing the main compartment an intake 'duct 20, in turn connected by a pipe 21 to a valve 22' which may he conveniently located at that side of the dash. 23 of the vehicle readily accessible to the operator of the vehicle, that is, toward the drivers seat 2 4, the dash 4and seat being customary parts of an automobile. v v Leading irom the valve 22is Aa pipe 25 'is carried to and enters a fuel reservoir 27 which may in the main lloe of ordinary construction, and is vceqoahle of withstanding such internal pressurees may beI needed inV the "operation of the invention. For 'con-- veniencc the fuel tank .or reservoir 27 is located under thedrivers seat 24 and the'v pipe 25 includes e stand p ipe 28'provided I Vwith a closure cap 29 having a nipple 30 for receiving the usuallhose connection of an air pump such as is customarily ein ployed in auto1nobiles. The stand pipe 28 is so situated andthe cap29 is so located as to hereadily accessible through the seat portion of the drivers seatl 2li. f

llnorder to distribute pressure a T. pipe 31' is located Within the t'anla 27 near the ipe 25 connecting to the. stein of the "l, Whicv stern is indicated at 32.5 The ends of the pipe 31 stop short of theuespectiveiieads of the tank 2422' Leading from the tank 27 at a high point thereof and shove the usual inf-izriniuin.A level n Vol? 4fuel therein is a pipe 33, the fuel being v,indicated at 34; The pipe 33 Yleads to and enters avalve casing 35 havingv a nipple endr36 screwed into the intake manifold 2.

,Within the casing 35 isa valve 37 having a valve stem 33 which may have a threaded 'portion*'397 whereby the valve 37 may he movedin 'the direction of its length powerd and from a valve seat 40 in the casing 35.

neewiee a length to be Within access of an operator seated on the opcrators seat 24: the rod 42 terminating in a handle 43 for convenience oi manipulation.

The carburetor 1l has a drain cock' il and the valve casing nipple 36 is provided with a cock i5.

The tank 27 may be filled with fuel through the stand pipe 23 after the cap 29 isreluoved. After the tank or reservoir is filled with fuel the cap 29 is replaced anrl by means (of an ordinary air pump attached to the nipple 30 pressure is established Within the tank 27 through the stand pipe andthe pipes 25, 32 and 3l, the valve 37 being in the meantime closed.

When it is desired to start the engine 1, such engine may be cranked in the usual manner, the valve 37 having been opened so that'the engine may draw a mixture of fuel vapor and air hy Way of the pipe 33 from that part of the tank 27 overlying the fuel' 34 therein. Such mixture of air and fuel vapor is suiliciently rich to provide a starting chargfe and the engine is started,

gasied hy the effects of the heat of the products ci combustion, and this gaseous matter becomes more and vmore highly Vlocated as it progresses through the pipe 7 'toward the outlet@ thereof. This heating of the gaseous fuel is intensi'ed on the passage of such fuel through the pipe 1l im mediately surrounding the exhaust pipe 10 and the gaseous fuel there becomes so highlyheated Athat it acts like a` fined gas and in the form of gas is converted into an explosive mixture in passing through the carbureter-.1ll where it receives a suitable supply Vof air, and then the explosive mixture enters the intake manifold 2 and' is distributed to the. engine cylinders to operate in the customary manner.

Should any eccurnulatiens voccur lin the valve member 35 or inthe carlcureter 11i requiring draining' or blowing ed' from time to time, this istaken care of hy the valves lliand.

lThe governor lo effectively prevents iooding of the heating pipes 7 and those following, While the arrangement of the casing 4 with the pipe 7. therein and the' continuing subjection of the vprelinainarily heated fuel to further heat in the pipe 1l insures thethorough gasification of such I iacutea t kerosene as a heavy fuel for the purpose,

this is only done for convenience of description, and that other heavyxfuels or mixtures 'of heavy and light fuels may be used.

i `Yls'herefound desirable the fuel pipes may Awithin 4the chamber A an be protected from heat radiation by suitable heat insulating means.

What 1s claimed is:-

l. Va orizing means-for the utilization of heavy liquid fuels for explosion engines, comprising an exhaust manifold havin an enlargement or chamber rising there rom immediately adjacent to and 'communicating with and. located above the exhaust 'ports leading from the engine cylinders, and

`an. extended fuel conve ing pipe lodged continued therefrom and embracing the exhaust pipe leadingpfromthe exhaust manifold and finally `comprising an exhaust manifold havin ,enlargement or chamber rising there rom dischar into the intake manifold.

` f2. Va orizmg means for the utilization of uels for explosion engines, an

heavy iquidU4 ediatel adjacent to and communicating with and ocated above the exhaust ports leadin from the engine cylinders, and an exten ed fuel conveying pipe lodged within the chamber and continued therefrom and embracing the exhaust pipe leading from the exhaust manifold and finally dischargf ing into the intake manifold, said Vaporiz- "aoi f liquid fuel under pressure and communicating means also including a reservoir for ing with the inlet end of the extended fuel conveying pipe, and there provided with a governor for controlling the amount of liquid fuel fed to the fuel conveying pipe within the chamber communicating with the exhaust manifold.'

3. A means for the utilization of keroseneV o1' the like as a fuel for explosion engines,

comprising an exhaust manifold for the engine having an extension rising from said manifold closely adjacent to the exhaust ports thereof, an extended fuel conveying pipe located within the exhaust manifold and extending therefrom and then coiled about the exhaust pipe leading from the exhaust manifold and finally discharging into the intake manifold of the engine, a reservoir for liquid fuel under pressure, and a pipe leading from the reservoir at a point above the liquid level therein and communicating with the intake manifold, said lastnamed' pi e including a controllable valve whereby el vapor under pressure may be delivered from the reservoir directly into the intake manifold at will.

4. Vaporizin r means for the utilization of heavy liqui fuelsfor explosion engines, comprising an exhaust manifold havin an enlargement `or chamber rising there rom immediately' adjacent to, communicating with and located above the exhaust ports leading from the engine, said enlargement being constructed separately from and secured to the manifold, and an extended fuelconveying pipe lodged Within the enlargement and communicating with the intake manifold of the engine.

5. Vaporizin means for the utilization of heavy liquid fuels lfor explosion engines, comprising an exhaust manifold havin an enlargement or chamber rising there rom immediately adjacent to, communicating with andv located above the, exhaust ports leading from the engine, said enlargement being constructed separately from and secured to the manifold, and an extended fuel-conveyin pipe lodged within the enlargen'ient an communicating with the intake manifold of the engine, the fuel pipe hetween the enlargement and the intake manifold being formed into a coil,v in close surrounding relation to the exhaust pipe leading from the exhaustmanifold.

n testimony, that I claim the foregoing as my own, I have hereto afiixed Iny signam ture in the presence of two witnesses.
